Estimate 528×321 to their nearest tens hundred and thousands

1.	Estimate 528×321 to their nearest tens hundred and thousands
Answer» Answer: In 475 the last two digits i.e., 75 is GREATER than 50. Therefore, 1 will be ADDED to the 3rd last DIGIT and the last two digits will become zero. After ROUNDING to nearest hundred we will get 500. In 225 the last two digit i.e., 25 is less than 50 Thus, the 3rd last will remain same and the last digit will become zero. After rounding to nearest ten we will get 200. Hence, the required product is 500×200=1,00,000

Answer:

In 475 the last two digits i.e., 75 is GREATER than 50.

Therefore, 1 will be ADDED to the 3rd last DIGIT and the last two digits will become zero.

After ROUNDING to nearest hundred we will get 500.

In 225 the last two digit i.e., 25 is less than 50

Thus, the 3rd last will remain same and the last digit will become zero.

After rounding to nearest ten we will get 200.

Hence, the required product is 500×200=1,00,000
